1.6 INTERPRETATION
DefinitionsGeneral: For the purposes of this worksection the definitions given in AS 4654.1 and AS 4654.2 and the following apply:
- Bitumen: A viscous material from the distillation of crude oil comprising complex hydrocarbons, which is soluble in carbon disulphide, softens when it is heated, is waterproof and has good powers of adhesion. It is produced as a refined by-product of oil.

. APP Bitumen: Bitumen modified with Atactic (meaning non-crystalline or amorphous) polypropylene wax to form a plastomeric sheet. The membrane is reinforced with fibreglass or non-woven polyester (NWP).
. SBS bitumen: Bitumen modified with Styrene Butadiene Styrene, a thermoplastic rubber that undergoes a phase inversion at elevated temperature and converts to an elastomeric material. The membrane is reinforced with fibreglass or non-woven polyester (NWP).
- Bond breaker: A system preventing a membrane bonding to the substrate, bedding or lining.
- Double detail joint: A joint formed by turning up and bonding the horizontal membrane to a vertical substrate and adding an overflashing of membrane material bonded to the vertical substrate and folded over and bonded to the horizontal membrane. In certain situations the double detail can be achieved by bonding an angle profile of membrane material to the junction prior to laying the membrane.
- Liquid applied: A water-based formulation which cures to form an elastomeric membrane.
- Polyurethane: Water or solvent based formulations which moisture cure to form an elastic rubber membrane.
- PVC membrane: Flexible plastic sheet membrane (vinyl).
- Slip sheet: A sheet used to isolate the membrane system from the supporting substrate or from the topping or mortar bedding. The most common material is polyethylene.
- Substrate: The surface to which a material or product is applied.
- Waterproofing systems: Combinations of membranes, flashings, drainage and accessories which form waterproof barriers and which may be:
. Loose-laid.
. Bonded to substrates.

04 ENCLOSURE 0411p DUROTECH waterproofing – external and tanking
Membrane: Extend root-resistant membrane at least 100 mm vertically above the soil fill level and secure.
Drainage: Grade the base of the planter to adequately sized drainage outlets and terminate the membrane in the outlets.
Drainage riser: Install a riser with drainage slots that extend from the membrane level to the top of the drainage cell. Extend the riser above the soil fill level and finish with a screw cap to provide access for drain clearing.
Protection board: Provide protection board to the full extent of the membrane including areas between soil level and the underside of flashings and cappings.
Drainage cell: Provide geo-filter fabric wrapped drainage cell to the base of the planter and turn geo-filter fabric up drainage riser at least 100 mm above drainage slots.
Cappings and flashings: Provide capping to the tops of planter walls to protect the membrane. Extend the capping to overlap the top of the protection board on the inside face of the planter wall. Where planter walls abut other walls, provide a flashing over the top of the membrane.
Membrane to below ground structuresMembrane: Externally apply membrane to all walls and return to horizontal surfaces to prevent water tracking around structure at joints and corners.
Protection board: Provide protection board to the full extent of the membrane.
Drainage cell: Provide geo-filter fabric wrapped drainage cell to vertical surfaces of the structure.
Reinforcement: Provide reinforcement to the membrane at junctions, corners and over joints to the manufacturer’s recommendations.

3.3 TESTING
Flood testApplication: Perform a flood test before the installation of surface finishes.
Moisture content measurement method: Conform to AS 1884 Appendix A
Set-up:
- Measure the wall/floor junction of adjacent spaces and of the slab soffit below for dryness.
- Record the result for each area.
© NATSPEC (Apr 18) 9 "[Insert date]"
04 ENCLOSURE 0411p DUROTECH waterproofing – external and tanking
- Dam the access openings and seal drainage outlets to allow 50 mm water level but no higher than 25 mm below the weir level of the perimeter flashings.
- Provide temporary overflows of the same capacity as the roof outlets to maintain the flood level.
- Fill space with clean water and leave overnight.
Evaluation:
- Make a visual inspection after a minimum period of 2 hours, of the wall/floor junction of adjacent spaces and of the slab soffit below for obvious water or moisture.
- Test the same areas for dryness using a moisture meter, and compare the results to the measurements taken before flooding.
Conformance:
- Evidence of water from the visual test: Failure.
- No visual evidence of water: Proceed with the moisture meter test.
- Test results indicating an increase in moisture before and after flooding: Failure.
Records: Submit records of all flood tests.
3.4 COMPLETION
ProtectionGeneral: Keep traffic off membrane surfaces after laying until bonding has set, 24 hours or to Durotech’s recommendation, whichever period is the longer.
Reinstatement: Repair or replace faulty or damaged work. If the work cannot be repaired satisfactorily, replace the whole area affected.
WarrantiesWaterproofing: Cover materials and workmanship in the terms of the warranty in the form of interlocking warranties from the supplier and the applicator.
